Interesting things about nails

The nails are one of the distinguishing features between primates, including humans, and other mammalian species. They are essentially flattened claws.

Fascinating Discoveries about Nails That Might Surprise You:

1. Nail Growth: On average, nails grow about 3.5 millimeters per month, while toenails grow about 1.6 millimeters per month, according to the American Academy of Dermatology.
2. White Spots on Nails: Contrary to popular belief, white spots on nails are not necessarily a sign of calcium deficiency. They are often harmless and could be the result of previous trauma or pressure on the hard part of the nail.
3. Composition Similarity: Both hair and nails are made up of keratin, a type of protein. A well-balanced diet rich in vitamins, antioxidants, proteins, and minerals contributes to the health of both hair and nails.
4. Gender Differences: Men tend to have faster-growing nails than women. However, this may be reversed during pregnancy for women, according to the American Academy of Dermatology.
5. Nail Biting and Stress: Nail biting is associated with anxiety and nervousness. It increases the risk of skin infections and damages the hard part of the nail. Bacteria from nails can enter the mouth and affect your health.
6. Nail Health and Overall Health: The overall health of the body can be monitored through nail health. Nutritional deficiencies can alter the color of the nails, and any unusual signs on the nails may indicate a need for dermatological consultation.
7. Seasonal Growth: Nails tend to grow faster in the summer than in the winter due to various factors such as age, genetics, and other environmental conditions.
8. Overuse of Nail Polish: Excessive use of nail polish can lead to increased risk of infection such as viral infections, warts, or nail fungus. Nails may become dry and brittle if chemical nail polishes are overused.
9. Skin Issues Related to Nails: Nearly half of all nail disorders are due to fungal infections (more common in toenails). Elderly individuals tend to have more skin and nail issues than younger individuals.
10. Stress Impact on Nail Growth: Stress, fatigue, and tension can inhibit nail growth by interfering with the body’s energy and nutrient transfer processes necessary for healthy skin, nails, and hair.
11. Protective Function of Nail Bed: The nail bed’s epidermis layer helps retain moisture and protects against the invasion of bacteria from the environment into the body.
12. Nail Hardness is Hereditary: The shape and growth of nails can be hereditary. However, external factors such as exposure to chemicals, frequent nail painting, and excessive use of soap or hand sanitizers can make nails dry and brittle.
13. Nail Nourishment: Nails can regenerate after injuries because they are supplied with a stable blood flow, oxygen, and nutrients necessary for cell repair. However, injuries below the hard keratinized layer of the nail can result in scarring and changes in nail shape.
14. Dominant Hand Nails Grow Faster: Nails on the dominant hand usually grow faster because they are used more frequently and are exposed to faster-growing factors.
15. Climate Influence: People living in warmer climates tend to have faster-growing nails because sunlight helps the body produce vitamin D, which promotes nail growth.
